Colinbus is no more active. Some Profiler owners are probably now "ex-users" or are searching for hardware/software solutions not to throw this good (rather) mechanic to the trash can.

I was happy to get one of this milling machine from a generous owner but the soft was not portable to another PC.

After some regulations and analyses, I made a milling machine usable via a parallel interface with a free software on PC (TURBOCNC in MSDOS ).I offered the whole system to the model making club of my municipality.

Obviously a parallel interface imposes constraints for evolution of the material supporting the software (PC) as well as in general evolutions.

I kept rehearsing the problem and arrived at a conclusion that a radical change was imperative:- upgrade to an USB interface;- replace the original card (from Colinbus)and its processor by a more evolutionary environment;- driving under any operating system (Linux, MacOS, Windows) thanks to one independent software on the HOST- use free softwares;- ...

Look at the result : look at PROFILER REVIVAL.Excuse the pretty poor quality of the video (the sequence was not selected for the festival) but you can see evolving with flexibility a 5mm diameter end mill in a depth of 4mm in MDF.Activation of the spindle motor by M code orders as well as a possible system of cooling by 230V plugs (1380W by plug).

Let me know your interest known for the project :- a PCB directly plugged on the PROFILER main board exists;- Some upgrades for tool length measure are simple to implement. The model you see on the video is rustic seemingly but reliable and of optical type. Its setting-up out of the working surface was made possible by the replacement of the ridiculous original spindle motor by a more serious but more cumbersome machine which, of the fact, shifts the working space partially out of the table (the lost working space become almost useless).

Isn't a PCB possible with GRBL without Arduino? I'm not an Arduino fan.

I'm interested in the placing of the PCB headers from processorboard to the driverboard and the connections I must made.

Grtz,

Theo

edit: I have the eagle files from Axemotion to connect the PulseBox NxtG with the profiler. I have the PCB ordered by elecrow today. The Pulsebox is also ordered.edit 2: The PCB is built up and placed on the Profiler. A tool sensor is placed. The Profiler works better as ever. The driving is smoother. Kay/Galaad has a lot of settings.
